Operation
G Warning
The TPMS does not warn you against incor-
rectly selected tire inflation pressures and
does not warn you when the tire pressure is
not properly selected for the respective vehi-
cle load. It warns you only when the pres-
sures of one or more tires decreases
significantly below the reference inflation
pressure which was stored at the time of cal-
ibration of the TPMS after you inflated the
tires.
Always make sure that you recalibrate the
TPMS after you have inflated the tires to the
recommended cold inflation pressure.
Always adjust the tire inflation pressure ac-
cording to the tire and loading information la-
bel on the driver's door B-pillar.
Underinflated tires wear excessively and/or
unevenly, adversely affect handling and fuel
economy, and are more likely to fail from be-
ing overheated.
Overinflated tires can adversely affect han-
dling and ride comfort, wear unevenly, in-
crease stopping distance, and result in
sudden deflation (blowout) because they are
more likely to become punctured or damaged
by road debris, potholes, etc.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case, bring the vehicle to a halt by care-
fully applying the brakes and avoiding abrupt
steering maneuvers.
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the recommended tire inflation pres-
sure on the vehicle label or the tire inflation
pressure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle label or the tire inflation pressure la-
bel, you should determine the proper tire in-
flation pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a h
low tire pressure indicator lamp when one or
more of your tires is significantly underin-
flated. Accordingly, when the h low tire
pressure indicator lamp comes on, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly underinflated
tire causes the tire to overheat and can lead
to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle's handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pres-
sure, even if underinflation has not reached
the level to trigger illumination of the
TPMS h low tire pressure indicator lamp.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the h low tire pressure indicator lamp.
When the system detects a malfunction, the
h indicator lamp will flash for approxi-
mately 1 minute and then remain continuous-
ly illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the h mal-
function indicator lamp is lit, the system may
not be able to detect or signal low tire pres-
sure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS h malfunction indicator lamp after
replacing one or more tires or wheels on your
vehicle to make sure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
